FIELD: data transmission.
SUBSTANCE: methods are claimed for processing data transmission in transmitter and receiver using native channel decomposition, channel inversion. In the transmitter, native decomposition of channel is performed to determine native modes of 3G network channel and to produce first set of control vectors; channel inversion is performed to produce weight coefficients, for example, one set for each native mode, used to minimize distortions introduced by inter-symbol interference, scaling values are produced, which characterize powers of transmission, distributed across native modes, where first set of control vectors, weight coefficients and scaling values are used to produce an impulse generation matrix, which is used for preliminary reduction of modulation symbols to meet required conditions before the transmission. In the receiver, native decomposition of channel is performed to produce second set of control vectors, which are used to produce an impulse generation matrix, used to reduce received symbols to meet required conditions in such a way, that orthogonal symbol streams are restored.
EFFECT: ensured high traffic capacity.
